I think they are going to shoot themselves in the foot if they release it on that date. Mario O release is very nearby to that date and it will eclipse the sale of Skyrim. In my opinion, November is the best date for them due to Nintendo haven't announced any first party game for that date yet.

"But if what we played is indeed fully representative of how the final game shapes up when running in mobile mode, the Switch port of Skyrim should be well worth checking out. We've tried playing the game on an Intel Atom-based tablet with integrated graphics and the experience is nothing like as good as this - if you're looking to play a fully portable Skyrim, you're looking at a larger gaming laptop to offer the visual feature set and performance the Switch version is offering."
